The paper analyzed the land use change on the coastal plain of south Hangzhou bay bank.

Granularity analyses of superficial sediments of Sparitina alterniflora flat on south coast of Hangzhou Bay;

<Abstrcat>Based on the Universal Soil Loss Equation (USLE), the authors analyse the function for soil conservation of agro-ecosystems and its eco-economic value in south coast of Hangzhou bay.

The paper discussed the granularity of superficial sediments of Spartina alterniflora salt marsh on the south coast of Hangzhouwan bay.

Based on analysis of the natural and soc-economic characters of south coast of Hangzhouwan bay and results of Costanza et al,the methods of ecological economics and ecology were applied to analyze the economic values on the south coast of Hangzhouwan bay.

According to the chemical analyses data of the groundwater samples from 129 hydrogeologic drill-holes,and the groundwater mineralization degree data of 1200 wells tested in the field,the hydrochemical environments of the groundwater in the south coast plain of Laizhou Bay,especially the hydrochemical environments of the shallow groundwater in the salt water intrusion area,have been studied.

By field investigation and water chemical monitoring, the groundwater environment of the shallow buried paleochannel zones and alluvial diluvial fans on the south coast plain of Laizhou Bay can be divided into 3 area: the salt groundwater district in the north, the transition district in the middle and the fresh groundwater district in the south.

Based on the data extracted from bathymetric maps and data obtained through hydrological and sediment surveys,this paper mainly deals with the evolution of siltation and erosion of the Jinhui tidal flat in the north of Hangzhou Bay.
